Looks totally corrupt. Functioning ITE firmware RAID produces a fairly
poor response which is why we fix up the DMA flag but does report the
volume size correctly.

What firmware rev is this mess coming from ?

Tejun - some of the reserved words indicate raid info, see the way the
driver uses them to report raid type/size.
